icinga2 php模块,Icinga2+Influxdb+Grafana搭建
Icinga2+Influxdb+Grafana搭建
注：可不要icingaweb2(即无icinga2页面)，Icinga2要求2.5版本以上
不过安装icingaweb2可方便排错，步骤略，需要php和mysql
icinga2下载网址：http://packages.icinga.org/epel/
influxdb下载网址：https://dl.influxdata.com/influxdb/releases/influxdb-1.3.6.x86_64.rpm
Grafana下载网址：https://s3-us-west-2.amazonaws.com/grafana-releases/release/grafana-4.5.2-1.x86_64.rpm
Icinga2安装步骤：
需要的包：libboost_system1、libboost_thread1、libboost_regex1、boost-license1、libboost_program_options1、icinga2、icinga2-bin、icinga2-common、icingacli、nagios-plugins
安装httpd：
# yum install httpd
额外包：fping、perl-NET-SNMP、perl-Crypt-DES (需先下载好)
# rpm -i libboost* boost-license (需先下载好)
# rpm -i icinga2* (需先下载好)
# rpm -i perl-Crypt-DES perl-NET-SNMP fping perl-Digest-SHA1 perl-Digest-HMACperl-Socket6
# rpm -i nagios-plugins-1.4.16-1.el6.rf.x86_64.rpm
# chkconfig icinga2 --level 35 on
Influxdb安装步骤：
# rpm -i influxdb-1.3.6.x86_64.rpm (端口8086)
配置文件路径：/etc/influxdb/influxdb.conf
数据存放路径：/var/lib/influxdb/data
日志路径：/var/log/influxdb/
# service influxdb start
# chkconfig influxdb --level 35 on
# influx
> create database icinga2;
> create user icinga2 with password 'xxxx';
> grant all on icinga2 to icinga2;
>quit
influxdb默认保留数据为168小时(即7天)，调整为1年命令：
> show retention policies on icinga2; (查看保留策略)
> alter retention policy "autogen" on "icinga2" duration 365d default; (对已有策略进行修改)
# vi /etc/icinga2/features-enabled/influxdb.conf
library "perfdata"
object InfluxdbWriter "influxdb" {
host = "127.0.0.1"
port = 8086
database = "icinga2"
host_template = {
measurement = "$host.check_command$"
tags = {
hostname = "$host.name$"
}
}
service_template = {
measurement = "$service.check_command$"
tags = {
hostname = "$host.name$"
service = "$service.name$"
}
}
enable_send_thresholds = true
enable_send_metadata = true
}
:wq
# icinga2 feature enable influxdb
# service icinga2 restart
Granfana安装步骤：
# rpm -i grafana-4.5.2-1.x86_64.rpm (端口3000)
# service grafana-server start
# chkconfig grafana-server --level 35 on
访问http://ip:3000 默认用户名、密码均为admin
Data Sources：Name:icinga2(可改) Type:InfluxDB Url:http://ip:8086 Access:proxy Database:icinga2 User:icinga2 Password:xxxxx
具体icinga2配置和grafana面板配置略
Grafana求多台服务器平均值：
面板——Graph——Metrics——Toggle Edit Mode：
SELECT mean("value") FROM "nrpe-mem" WHERE "hostname" =~ /shhu*/ and "metric" = 'Per' AND $timeFilter GROUP BY time($interval)
icinga influxdb面板下载网址：
记得icinga2中需启用ping4监控(该面板依据ping4抓取服务器名)
